Remove any sd or ssd disk to be managed by HDLM from VxVM control.

to the VxVM documentation. If HDLM has been installed, remove any such sd or

ssd device from VxVM control as directed in 3.13.3 Removing Devices from

configurations of all the hosts are identical (host type; HBA type, number, slots; the

number of paths and the HUBs and switches through which each path passes; and the

storage ports and LUN used by each LU).
